TIP 2, 3 (Triad 2, 3 / NNS)
Nova (similar to TIP 2 and 3)
[US Navy]
The TIP 2 and 3 (Transit Improvement Program) satellites used a simplified form of the Triad 1 drag correction system. Pulsed plasma thrusters were used for drag correction maneuvers. The satellites were used operationally in the Transit navigation system. Slightly improved versions were built as Nova.
